Originally perceived as a cheap and plentiful source of power, the commercial use of nuclear energy has been controversial for decades. Worries about the dangers that nuclear plants and their radioactive waste posed to nearby communities grew over time, and plant construction in the United States virtually died after the early 1980s. The 1986 disaster at Chernobyl only reinforced nuclear power's negative image. Yet in the decade prior to the Japanese nuclear crisis of 2011, sentiment about nuclear power underwent a marked change. The alarming acceleration of global warming due to the burning of fossil fuels and concern about dependence on foreign fuel has led policymakers, climate scientists, and energy experts to look once again at nuclear power as a source of energy.
In this accessible overview, Charles D. Ferguson provides an authoritative account of the key facts about nuclear energy. What is the origin of nuclear energy? What countries use commercial nuclear power, and how much electricity do they obtain from it? How can future nuclear power plants be made safer? What can countries do to protect their nuclear facilities from military attacks? How hazardous is radioactive waste? Is nuclear energy a renewable energy source? Featuring a discussion of the recent nuclear crisis in Japan and its ramifications, Ferguson addresses these questions and more in Nuclear Energy: What Everyone Needs to Know(r), a book that is essential for anyone looking to learn more about this important issue.

The purpose of this publication is to assist Member States in developing comprehensive contingency plans for computer security incidents with the potential to impact nuclear security and/or nuclear safety. It provides an outline and recommendations for establishing a computer security incident response capability as part of a computer security programme, and considers the roles and responsibilities of the system owner, operator, competent authority, and national technical authority in responding to a computer security incident with possible nuclear security repercussions.

Energy demand in the United States is expected to continue to grow over the coming decades, and the Department of Energy (DOE) considers nuclear energy to be one way to help meet this increased demand without producing air pollution. However, the current domestic commercial nuclear reactor fleet, consisting of 99 large light water reactors (LWRs) that provide about 20 percent of U.S. electricity is aging, and some reactors have shut down in recent years. LWRs use light, or ordinary, water to cool the reactor. New reactor concepts are under development as alternative energy options. Light water small modular reactors (SMRs) have some similarities, including the coolant used, to the existing large LWRs, and advanced reactors differ more from the large LWRs. Both new reactor concepts differ from the existing large LWRs in potential applications. This book discusses the status of light water SMR and advanced reactor concepts under development; the intended benefits of these new reactor concepts; and the challenges associated with developing and deploying these new types of reactors. Furthermore, the book describes DOE's Office of Nuclear Energy's (NE) approach to advanced nuclear reactor research and development (R&D) and examines how NE plans and prioritises its advanced reactor R&D activities, including deploying an advanced reactor.

Uranium is a naturally occurring, ubiquitous heavy metal. In various chemical forms, natural uranium is found in all soils, rocks, seas and oceans. It is also present in drinking water and food. Uranium was discovered in 1781 by Klaprot, a pharmacist in Berlin, in the Joachisthal silver mines. This book starts with a short history of uranium. It continues with the legacy of uranium mining and the authors go on to discuss the environmental and health effects of depleted uranium, which has the unique potential to threaten all natural resources, including human society because of its radiotoxic effects. Uranium migration properties are explored through the geological structures and the groundwater systems based on the determination of its total concentration essential for environmental studies. Other chapters examine the recovery of uranium from phosphate rock; the influence of uranium on the environment and the studies of content of uranium in soil, building materials, drinking water and even in the urine of specific population such as in the Czech Republic, a uranium rich territory; the types of uranium deposits; uranium bioremediation as an eco-friendly, promising approach, which will play an irreplaceable role in global nuclear energy development; discussions on uranium as one of the most widespread contaminants in groundwater in mining areas, as well as in surface waters in Brazil; and an examination of fuel materials that have been developed for use in nuclear power reactors including uranium. Bulk uranium-based systems are very complex and it is difficult to draw unambiguous conclusion on their properties and reaction mechanisms from experiments. Therefore in this book, laboratory experiments using simple model systems - thin films, for single effect studies which have a ground-breaking nature are explored in detail in this book.

This book deals with urgent and timely issues related to radiation health effects and protection that are examined by both young researchers as well as experts. The book is organized into three major sections: biological responses, population monitoring and approaches to protection from radiation exposure. Contributors have provided state of the art research in their respective chapters. Radiation action produces damage to multiple targets in the exposed cells or human body and understanding of molecular mechanisms of the underlying processes becomes central to the monitoring of effects and health consequences of radiation exposure. Many experts have highlighted the outcome of epidemiological studies on human populations in high background radiation areas in different locations around the world as well as consequences and scopes for mitigating radiation health effects after radiation accidents such as Chernobyl in Ukraine and the Fukushima Daiichi Accident in Japan. This book also provides important direction for treatment of radiation for exposed victims. In the concluding chapters, contributors have provided new approaches for protection against ionizing radiation exposure. This book contains rich content on basic aspects of radiation induced cellular response which may give deeper insight to beginners in research, teaching, industry and regulatory authorities for basic understanding of radiobiological processes and molecular mechanisms. The book will prove an authentic reference source for updates in radiation science. It is hoped that students, teachers, experts, safety officers, regulatory officials and policy-makers will find the book handy for gaining a broad view of radiation damage to biological systems, monitoring health consequences and for new approaches in developing effective protection against radiation exposure.

The magnitude 9.0 Great East Japan Earthquake occurred on March 11, 2011, claiming over 20,000 lives. It crippled the Fukushima Daiichi Nuclear Power Plant, whose hydrogen-air explosions contaminated wide areas around Fukushima with radionuclides. The number of evacuees initially totaled 328,903, but has been reduced to 263,392 as of February 13, 2014. More than half of the evacuees (132,500) consist of Fukushima residents, and 67% of whom have experienced mental or physical disorders. Indeed, refugee life is so difficult that many Fukushima families have been affected by suicide, divorce, separation of family members, migration and settlement to other places, mental illness, etc. The difficulty is caused by the fear of low-dose radiation induced by the LNT model which claims that radiation cancer risk is linearly proportional to dose without any threshold. Careful scrutiny of the model, however, clearly indicates that the linearity is invalid; low dose radiation is not hazardous, but is even beneficial or hormetic because of the adaptive response to radiation. This book provides ample evidence to negate the LNT model. This book is primarily compiled to get rid of the spell of the LNT model and release Fukushima people from undue torture. The book would also be useful to the public in general who have CT scans and have concerns. In addition, the people who use radiation world-wide such as nuclear power plant workers, radiation researchers, radiologists, and X-ray operators would be relieved to learn from reading this book that the alleged risk of low-dose radiation is illusionary and that the low-dose radiation is even beneficial. Policy makers of nuclear energy and radiation who are working for governmental and/or regulatory agencies are also recommended to read this book. Severe guidelines from a safety standpoint sometimes entrap people into a fear-stricken situation rather than save them, as no one was killed by radiation directly, but more than 1,000 people have been killed by the fear of radiation secondarily in Fukushima. By the same token, this book is recommended to civil activists and journalists who emphasise dangers of low-dose radiation and raise fear of low-dose radiation. It is the time to shed new scientific light on the outdated LNT model.

A electric glow discharge is a type of plasma formed by passing a current at 100 V to several kV through a gas at low pressure, usually argon or another noble gas. It is found in products such as fluorescent lights and plasma-screen televisions, and is used in plasma physics and analytical chemistry. A tokamak is a machine producing a toroidal magnetic field for confining a plasma which is characterised by azimuthal (rotational) symmetry and the use of a plasma-borne electric current to generate the helical component of the magnetic field necessary for stable equilibrium. It is one of several types of magnetic confinement devices, and is one of the most-researched candidates for producing controlled thermonuclear fusion power. This book discusses and presents current data on both glow discharges and tokamaks.

The importance of the radioactive minerals occurring at the Pocos de Caldas plateau for the establishment of the Brazilian Nuclear Energy Program has been recognised world-wide. The interest in uranium in the present days as a consequence of its use as a nuclear fuel coupled to its price in the international market has lead to intense debate, mainly due to questions related to global warming. Thus, all initiatives/studies directed to a better knowledge/management of this element in the environment are welcome and needed. This book describes many results obtained on the analysis of natural radionuclides in different compartments, considering their distribution in (un)disturbed environments, as well as consequences of the anthropogenic actions and possible lessons that can be learned from the past uranium exploration activities held at the Pocos de Caldas caldera.

The Department of Energy (DOE)proposes under the Global Nuclear Energy Partnership (GNEP) to build facilities to begin recycling the nation's commercial spent nuclear fuel. GNEP's objectives include reducing radioactive waste disposed of in a geologic repository and mitigating the nuclear proliferation risks of existing recycling technologies. DOE originally planned a small engineering-scale demonstration of advanced recycling technologies being developed by DOE national laboratories. While DOE has not

Questions regarding the advancement of the technology for production and regeneration of nuclear fuel and to the further perfection of the nuclear fuel cycle are very significant when determining the ultimate costs of electrical energy produced at nuclear power stations as well as for safety. This 2nd edition, supplemented and augmented, of this ground-breaking book analyses the role of plasma and high frequency processes.

This publication provides guidance on implementing the principle of confidentiality and on the broader aspects of information security (i.e. integrity and availability). It assists States in bridging the gap between existing government and industry standards on information security, the particular concepts and considerations that apply to nuclear security and the special provisions and conditions that exist when dealing with nuclear material and other radioactive material. Specifically it seeks to assist States in the identification, classification, and assignment of appropriate security controls to information that could adversely impact nuclear security if compromised.

After Atomic Junction, along the Haatso-Atomic Road there lies the Ghana Atomic Energy Commission, home to Africa's first nuclear programme after independence. Travelling along this road, Abena Dove Osseo-Asare gathers together stories of conflict and compromise on an African nuclear frontier. She speaks with a generation of African scientists who became captivated with 'the atom' and studied in the Soviet Union to make nuclear physics their own. On Pluton Lane and Gamma Avenue, these scientists displaced quiet farming villages in their bid to establish a scientific metropolis, creating an epicentre for Ghana's nuclear physics community. By placing interviews with town leaders, physicists and local entrepreneurs alongside archival records, Osseo-Asare explores the impact of scientific pursuit on areas surrounding the reactor, focusing on how residents came to interpret activities on these 'Atomic Lands'. This combination of historical research, personal and ethnographic observations shows how Ghanaians now stand at a crossroad, where some push to install more reactors, whilst others merely seek pipe-borne water.

This book encompasses many different topics in the field of nuclear safety and answers the need for an accessible introductory text to complement industry guidance. It focuses on the principles and applications of nuclear safety, guiding the reader through the 'why' and the 'how' of constructing a nuclear safety case. The theory is enhanced by the provision of examples on how safety cases may tackle a particular problem. Each nuclear site licensee has its own way of undertaking nuclear safety although there is much common ground. The book adopts a consensus approach to the various methodologies used in the industry and armed with such knowledge, an individual should have a good grounding for the application of nuclear safety in the manner required for their industry. Introduction to Nuclear Safety describes why we pursue nuclear safety, including the legal, financial and moral reasons. The fundamental concept of reducing risks to as low as reasonably practicable in the nuclear industry is discussed and the safety case life-cycle from design to commissioning to operations and decommissioning is described. Typical safety case methodologies are also discussed. In considering the applications of nuclear safety, examples of how to undertake an assessment are given. Producing a safety case is not solely a theoretical exercise; it must be implemented and adopted for use within the plant. Therefore, the book describes how safety case documents can be utilised within the plant. The book assumes only a relatively basic knowledge of physics, engineering and mathematics but the interested reader can find more detailed texts in the bibliography.

Since the dawn of the Atomic Age, nuclear experts have labored to imagine the unimaginable and prevent it. They confronted a deceptively simple question: When is a reactor “safe enough� to adequately protect the public from catastrophe? Some experts sought a deceptively simple answer: an estimate that the odds of a major accident were, literally, a million to one. Far from simple, this search to quantify accident risk proved to be a tremendously complex and controversial endeavor, one that altered the very notion of safety in nuclear power and beyond.   Safe Enough? is the first history to trace these contentious efforts, following the Atomic Energy Commission and the Nuclear Regulatory Commission as their experts experimented with tools to quantify accident risk for use in regulation and to persuade the public of nuclear power’s safety. The intense conflict over the value of risk assessment offers a window on the history of the nuclear safety debate and the beliefs of its advocates and opponents. Across seven decades and the accidents at Three Mile Island, Chernobyl, and Fukushima, the quantification of risk has transformed both society’s understanding of the hazards posed by complex technologies and what it takes to make them safe enough.

The development and implementation of an appropriate infrastructure to support the successful introduction of nuclear power and its safe, secure, peaceful and sustainable application is an issue of central concern, especially for countries that are considering and planning their first nuclear power plant. In preparing the necessary nuclear infrastructure, there are several activities that need to be completed. These activities can be split into three progressive phases of development. This publication provides a description of the conditions expected to be achieved by the end of each phase to assist with the best use of resources. 'Milestones' refer to the conditions necessary to demonstrate that the phase has been successfully completed.

In using risk-informed approaches for ensuring safety of operating nuclear power plants (NPPs), risk importance measures obtained from probabilistic risk assessments (PRAs) of the plants are integral elements of consideration in many cases. Obtaining these measures in appropriate forms is helpful for decision makers and can facilitate the use of risk information.

This publication is a revision of IAEA-TECDOC-1212 which primarily focused on enhancing the utilization of existing research reactors. This updated version also provides guidance on how to develop and implement a strategic plan for a new research reactor project and will be of particular interest for organizations which are preparing a feasibility study to establish such a new facility. This publication will enable managers to determine more accurately the actual and potential capabilities of an existing reactor, or the intended purpose and type of a new facility. At the same time, management will be able to match these capabilities to stakeholders/users' needs and establish the strategy of meeting such needs. In addition, several annexes are presented, including some examples as clarification to the main text and ready-to-use templates as assistance to the team drafting a strategic plan.

This monograph summarizes the major developments on nuclear reactor thermal-hydraulics over the last fifty years, primarily for the water-cooled reactors, and provides a direction for the future thermal-hydraulic developments for water-cooled, including small modular reactors or SMR, and Generation IV reactors. This includes discussion on the steady-state reactor thermal hydraulics including subchannel analysis, evolution of emergency core cooling systems (ECCS) from active to fully passive systems to remove the decay heat, and development and consolidation of the best-estimate safety analysis methodology. With substantial increase in computing power, the computational fluid dynamics (CFD) tools for single-phase and multi-phase flows are being used more these days to address some of the important reactor thermal-hydraulics phenomena which could not be analyzed earlier using the traditional one-dimensional or coarse three-dimensional analysis tools. Development of multi-physics methodology encompassing neutronics, thermal-hydraulics, thermal-mechanical and coolant chemistry has also started.
